Pneumatic equipment should be maintained only by persons
trained and experienced in the maintenance of such equipment.
Supply Clean Air. Foreign material lodging in valves is a major cause
of breakdowns. The use of an air filter located close to the valve is
strongly recommended. The filter bowl should be drained regularly, and
if its location makes draining difficult, the filter should be equipped with
an automatic drain.
Check Lubricator Supply Rate. A lubricator should put a fine oil mist
into the air line in direct proportion to the rate of air flow. Excessive
lubrication can cause puddling in the valve and lead to malfunctions.
For most applications an oil flow rate in the lubricator of one drop per
minute is adequate (note that this valve itself does not require air line
lubrication, but some optional adaptors do, i.e., air index, etc.).
Compatible Lubricants. Although this valve does not require air line
lubrication, it may be used with lubricated air being supplied to other
mechanisms. Some oils contain additives that can harm seals or other
valve components and so cause the valve to malfunction. Avoid oils with
phosphate additives (e.g., zinc dithiophosphate), and diester oils; both
types can harm valve components. The best oils to use are generally
petroleum base oils with oxidation inhibitors, an aniline point between
180°F (82°C) and 220°F (104°C), and an ISO 32 or lighter viscosity.
Some compatible oils are listed above at the right. These oils, although
believed to be compatible, could change without notice because
manufacturers sometimes reformulate their oils. Therefore, use oils
specifically compounded for air line service. If it is a synthetic oil, contact
the oil manufacturer for compatibility information.
Cleaning the Valve. If the air supplied to the valve has not been well
filtered, the interior of the valve may accumulate dirt and varnish which
can affect the valve’s performance. A schedule should be established
for cleaning all valves, the frequency depending on the cleanliness of
the air being supplied.
IMPORTANT NOTE: Please read carefully and thoroughly
all the CAUTIONS and WARNINGS on page 4.

VALVE MAINTENANCE
To clean the valve use any good commercial solvent.
Do not scrape varnished surfaces. Also do not use
chlorinated solvents or abrasive materials. The former
damages seals, and abrasives can do permanent
damage to metal parts. Before reassembling the valve,
lubricate all sliding surfaces with a grease such as
MobilGrease 28.
Electrical Contacts. In the electrical circuits associated
with the valve solenoids, keep all switches or relay
contacts in good condition to avoid solenoid malfunctions.
Replace Worn Components. In some cases it is not
necessary to remove the valve from its installation for
servicing. However, turn off the electrical power to the
valve, shut off the air supply, and exhaust the air in the
system before beginning any disassembly operation.
Service kits for these valves are listed on page 3.
